@badrihippo Credit Cards are full of redundant methods for getting account information off them
1. The numbers being printed are from when the merchant would transfer by writting them out, with a pen
2. Embossing to work with card imprinters
3. Mag stripe to work with mag stripe readers
In Norway these days it is 90% contactless with the very occasionally insert of the chip. You can remove all 3 of the above and it would not really matter at all.
